------------------------------------
Big thanks to [~clayb] and his team for bringing this one to our attention!
> Add per-table latency histograms
> --------------------------------

> Key: HBASE-19285
> URL: https://issues.apache.org/jira/browse/HBASE-19285
> Project: HBase
> Issue Type: Bug
> Components: metrics
> Reporter: Josh Elser
> Assignee: Josh Elser
> Priority: Critical
> Fix For: 2.0.0, 1.4.0, 1.3.3
>
>
> HBASE-17017 removed the per-region latency histograms (e.g. Get, Put, Scan at
> p75, p85, etc)
> HBASE-15518 added some per-table metrics, but not the latency histograms.
> Given the previous conversations, it seems like it these per-table
> aggregations weren't intentionally omitted, just never re-implemented after
> the per-region removal. They're some really nice out-of-the-box metrics we
> can provide to our users/admins as long as it's not detrimental.
